The neutron has no charge, therefore the charge to mass ratio for the neutron is zero.
It is a simple ratio charge/mass or e/m .
Compared to the (charge/mass) ratio of the electron:-- The (charge/mass) ratio of the proton is much smaller; although the proton charge is equal to the electron charge, the proton mass is much larger, by a factor of more than 1,800.-- The (charge/mass) ratio of the neutron is zero, because the neutron charge is zero.
The charge and mass ratio of proton is constant, the positive particles found during discharge tube experiment are nuclei of atoms which have different charge and mass ratio.
Modern Mass Spectrometry is the alternative method to measure the charge to mass ratio of an electron.
Mass of a Proton = 1.6726x10-27 kg Mass of a Neutron = 1.6749x10-27 kg The ratio is then: 0.99864
If you're talking about mass spectrometry, the measurements made for each isotope during the detection process are abundance and mass to charge ratio.
Because the charge/mass ratio of a nucleus is smaller than the charge/mass ratio of an electron
J.J.Thompson determined the electron charge to mass ratio. His results, however, were off by almost a factor of two, although they were consistent, leading us to believe there was some systematic error in his measurements.
They have the same mass/charge ratio.
It is Hydrogen.
Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
